Precision Fasteners

Standard catalogue to fully bespoke micro-hardware

Overview
AutomotiveAerospaceDefenseMarine

A fastener is only as good as its weakest tolerance. Our fastener division combines cold-heading throughput with machined-fastener precision, so you can source everything from a standard bolt to a fully bespoke titanium micro-screw without switching suppliers — or compromising traceability.

Every lot is produced against a documented process, with material certs, torque-tension data and dimensional reports available on request. When the catalogue does not have what your assembly needs, we design and manufacture the special hardware that does.
